Definitions
- Heat transfer papers for transferring letters, figures, designs, and other shapes have developed into a significant industry.
- shapes When heat transfer paper is used for transferring letters, figures and designs to a substrate, there have been a variety of transfer methods.
- the desired shape can be printed onto the heat transfer paper, in advance, on a substrate with a thermally transferable material according to a proper printing method (e.g., silk screen printing, gravure printing, offset printing, etc.), and then the shape is transferred to the substrate.
- a proper printing method e.g., silk screen printing, gravure printing, offset printing, etc.
- Another exemplary method includes applying a thermally transferable layer on the whole surface of the heat transfer paper, cutting out the desired shape(s) from the heat transfer paper, and then transferring the shape to a substrate using heat and pressure (e.g., applied to an ironing sheet).
- Methods where the shapes are formed through printing can be suitable for preparing a large amount of heat transfer materials of the same letters or figures and designs.
- the relatively high costs and expenses involved in printing can lead to high costs per unit, especially for small scale production.
- Methods where a heat transfer sheet having a thermally transferable layer applied onto the whole surface of a base which layer is cut into the desired shape can have a number of ways to apply the shapes to the substrate.
- the shapes can be cut fully out of the heat transfer paper (i.e., the shape is cut through the entire thickness of the heat transfer sheet), and then arranged and applied to the substrate to be transferred.
- this method can lead to inaccuracies and difficulties in exactly replicating the design when multiple shapes must be individually arranged together (e.g., multiple letters forming a word).
- the shape can be cut into the heat transfer material only to the base sheet (i.e., leaving the base sheet intact).
- the shape can be cut using an automatic cutting machine controlled by a computer.
- transfer tape can be utilized to remove the shape(s) from the heat transfer material and position it (them) on the substrate.
- the areas surrounding the shape to be transferred to the substrate must be removed (i.e., weeded) from the transfer material.
- the remaining shape on the base sheet can be lifted from the base sheet and laid onto the substrate.
- the tape must be able to temporarily bond to the shape, and the substrate, withstand the transfer process, and then be removable from the transferred shape and the substrate without damaging either.
- Such selection of tape can be difficult, and the tape can significantly increase the cost of the transfer as suitable tape can be expensive.
- the shape in another alternative method, can be cut into the heat transfer material leaving the base sheet intact, and the areas surrounding the shape can be removed leaving only the shape on the base sheet. Then, the shape can be transferred to the substrate.
- removing the areas around the shape can be difficult using presently available heat transfer sheets.
- the removal of the unnecessary portions of the transfer layer by peeling can be relatively easy when the thickness of the transfer layer which is applied onto the base sheet over a releasing layer is thick.
- such thick transfer layers can lead to overly thick shapes transferred onto the substrate and are subject to more wear over time.
- removing the unwanted portion of a thin transfer layer is difficult and can lead to deformation in the shape to be transferred.
- a method of transferring an image to a substrate is generally provided.
- a heat transfer material can be partially cut to define a shape with cuts made into the heat transfer material (i.e., into its thickness).
- the heat transfer material includes a transferable portion overlying a release layer overlying a base sheet such that the cuts are made into the heat transfer material through the transferable portion while leaving the release layer and base sheet uncut.
- the transferable portion of the heat transfer material can be removed from the base sheet in an area surrounding the shape. Then, the heat transfer material can be positioned adjacent the substrate such that the transferable portion defined by the shape contacts the substrate. Heat and pressure can be applied to the heat transfer material. Thereafter, the base sheet can be removed.
- Embodiments can also include a peel force of about 10 to about 100 grams (e.g., about 25 to about 50 grams) used to remove the transferrable portion of the heat transferrable material from the base sheet. Additional embodiments can include using a polymeric binder and powdered thermoplastic polymer in a ratio of from about 2:1 to about 20:1 in a color layer and embodiments where the color layer is cross-linked or non-cross-linked.
- a top layer may be used that includes a film-forming binder and a powdered thermoplastic polymer configured to melt and flow at the transfer temperature such that the top layer bonds to the substrate.

- molecular weight generally refers to a weight-average molecular weight unless another meaning is clear from the context or the term does not refer to a polymer. It long has been understood and accepted that the unit for molecular weight is the atomic mass unit, sometimes referred to as the “dalton.” Consequently, units rarely are given in current literature. In keeping with that practice, therefore, no units are expressed herein for molecular weights.
- cellulosic nonwoven web is meant to include any web or sheet-like material which contains at least about 50 percent by weight of cellulosic fibers.
- the web may contain other natural fibers, synthetic fibers, or mixtures thereof.
- Cellulosic nonwoven webs may be prepared by air laying or wet laying relatively short fibers to form a web or sheet.
- the term includes nonwoven webs prepared from a papermaking furnish.
- Such furnish may include only cellulose fibers or a mixture of cellulose fibers with other natural fibers and/or synthetic fibers.
- the furnish also may contain additives and other materials, such as fillers, e.g., clay and titanium dioxide, surfactants, antifoaming agents, and the like, as is well known in the papermaking art.
- polymer generally includes, but is not limited to, homopolymers; copolymers, such as, for example, block, graft, random and alternating copolymers; and terpolymers; and blends and modifications thereof.
- polymer shall include all possible geometrical configurations of the material. These configurations include, but are not limited to isotactic, syndiotactic, and random symmetries.
- thermoplastic polymer is used herein to mean any polymer which softens and flows when heated; such a polymer may be heated and softened a number of times without suffering any basic alteration in characteristics, provided heating is below the decomposition temperature of the polymer.
- thermoplastic polymers include, by way of illustration only, polyolefins, polyesters, polyamides, polyurethanes, acrylic ester polymers and copolymers, polyvinyl chloride, polyvinyl acetate, etc. and copolymers thereof.
- Methods of forming an image on a substrate are generally provided, along with the heat transfer sheets for use in such methods.
- the presently disclosed methods can transfer a shape or shapes to a substrate without the use of a transfer tape and without the use of an ironing sheet, effectively reducing the cost per transfer of the shapes.
- the presently disclosed methods are less time consuming and less prone to errors due to the ease of weeding the shapes to be transferred to the substrate.
- FIG. 1 shows an exemplary heat transfer material 10 for use according to methods of the present disclosure.
- the heat transfer material 10 includes a transferable portion 11 .
- the transferable portion 11 includes a top layer 12 , an optional intermediate layer 14 , a color layer 16 , and a tie layer 18 .
- the transferable portion 11 overlies a non-transferable portion of a release layer 20 on a base sheet 22 .
- Transferring an image to a substrate can be achieved by cutting a shape partially into a heat transfer material 10 such that the shape (i.e., the image) is defined by cuts in the heat transfer material through the transferable portion while leaving the release layer and paper substrate uncut.
- FIG. 2 shows cuts 15 through the thickness of the heat transfer material 10 defined by the transferable portion 11 while leaving the release layer 20 and the base sheet 22 uncut.
- the cuts 15 can define a shape 17 .
- the cuts can be achieved through plotter cutting via a plotter cutter (also known as a cutting plotter).
- Plotter cutters are well known in the art and are readily available commercially. Suitable plotter cutters for use with the present invention can include, but are not limited to, roll-feed cutting plotters, flatbed cutting plotters, desktop cutting plotters, etc.
- a plotter is a graphics printer that uses a pen or pencil to draw images, and works closely with a computer's imaging software to produce a final picture or object.
- Plotters differ from printers in that plotters use continuous lines to create images. Like printers, plotters are connected to computers and are used to produce complex images and text.
- Cutting plotters are formed by replacing a plotter's pen with a knife or sharp razor blade.
- the cutting plotter may also contain a pressure control device that regulates how firmly the knife presses down on the material, to control the depth of the cuts formed.
- cutting plotters can be operated by moving the cutter's knife rather than the material itself (e.g., flatbed cutting plotters), many cutting plotters working with flexible material continue to use the sliding roller featured in pen plotters (e.g., roll-feed cutting plotters).
- Suitable plotter cutters capable of cutting the desired graphics into a workpiece and controlling the depth of the cuts are available commercially from many manufactures, including but not limited to, Graphtec America Inc. (Santa Ana, Calif.) under series designated FC8000 and CE5000; Roland DG Corp. (Japan) under series VersaUV LEC; and Cricut® cutters (from Cricut®, Spanish Fork, Utah a division of Provo Craft and Novelty, Inc.), just to name a few.
- the area of the heat transfer material 10 not defining the shape 15 can be referred to as the extra area 19 of the transferable portion 11 of the heat transfer material 10 .
- This extra area 19 of the transferable portion 11 of the heat transfer material 10 can be removed from the heat transfer material 10 to leave a transitional heat transfer sheet 30 .
- the transfer portion 11 remaining on the transitional heat transfer sheet 30 (i.e., shape 15 ) defines the mirror image of the shape to be transferred on the final substrate.
- the peel force required to remove the extra area 19 is relatively light such that the user can remove the extra area 19 by hand without the use of lifting tape or other tools.
- the extra area 19 can be weeded from the heat transfer material 10 relatively easily without risk of damaging the material forming shape 15 or the base sheet 22 .
- the peel force can be about 10 grams to about 100 grams, more desirably about 25 grams to about 50 grams as measured by using an Instron 5500R Tensile Tester (Instron Corp., Norwood, Mass.) set to measure the average load required to peel a 2 inch wide strip of transferable portion 11 away from the base sheet 22 and release 20 , the testing being performed at a rate of 300 mm/minute.
- the transitional heat transfer sheet 30 can be positioned adjacent to the substrate such that the surface 13 of the top layer 12 of the transferable portion 11 defined by the shape 15 contacts the substrate 40 , such as shown in FIG. 4 .
- Heat (H) and pressure (P) then can be applied to the base sheet 22 to transfer the transferable portion 11 to the substrate 40 .
- the heat (H) and pressure (P) can be applied to the transitional heat transfer sheet 30 via a heat press, an iron (e.g., a conventional hand iron), or any suitable heating and pressing process.
- the heat (H) and pressure (P) can be applied to the transitional heat transfer sheet 30 for a time sufficient to cause at least the top layer 12 , the intermediate layer 14 (when present), and an non-cross-linked color layer 16 (when present) to soften and melt.
- Temperatures at the transfer can be from about 120° C. or greater, such as from about 120° C. to about 220° C., and can be applied for a period of a few seconds to a few minutes (e.g., from about 5 seconds to about 5 minutes).
- the meltable layers soften and flow into the substrate 40 to bond the shape 15 to the substrate 40 .
- the base sheet 22 can be removed before the transitional heat transfer sheet 30 can substantially cool (i.e., while the transitional heat transfer sheet 30 is still hot) as a hot peel or after allowing the transitional heat transfer sheet 30 to cool as a cold peel.
- the tie layer 18 can split when the base sheet 22 is removed.
- a first portion of the tie layer 18 remains on the base sheet 22 and is removed from the substrate 40 , while a second portion of the tie layer 18 is transferred to the substrate 40 along with the rest of the transferable portion 11 .
- the phrase “hot peelable transfer process” refers to a process wherein one or more meltable layers is still in a molten state when a non-transferable portion (i.e., the release layer 20 and the base sheet 22 ) of a transitional heat transfer sheet 30 is removed from the substrate 40 after applying heat and pressure. Such a process allows release of the transitional heat transfer sheet 30 via splitting of the melted tie layer 18 .
- the tie layer 18 can release from the release layer 20 such that substantially all of the tie layer 18 is transferred to the substrate 40 .
- This cold peel process results in the transfers shown in FIGS. 5 a - 5 c where the tie layer 18 is completely transferred to the substrate 40 with the rest of the transfer portion 11 of the transitional heat transfer sheet 30 .
- the top layer 12 defines an outer surface 13 of the heat transfer material 10 and will ultimately contact the substrate 40 to which the shape is to be transferred.
- the top layer 12 is configured to melt and flow at the transfer temperature such that the top layer 12 can bond to the substrate 40 .
- the top layer can protect the underlying layers (e.g., the optional intermediate layer 14 and/or the color layer 16 ) prior to use of the heat transfer material 10 .
- the top layer 12 can have essentially no tack at room temperatures (e.g., about 20° C. to about 25° C.) while melting and flowing into the substrate at the transfer temperatures.
- the top layer 12 of the heat transfer material 10 is configured to melt and flow into the substrate 40 during the application of heat (H) and pressure (P) in the transfer process.
- the top layer 12 generally softens and melts at the transfer temperature, and in particular embodiments, at temperatures lower than the transfer temperature.
- the top layer 12 can melt at temperatures of about 65° C. to about 180° C., such as about 80° C. to about 130° C.
- the top layer 12 since the top layer 12 is exposed as an outer surface of the heat transfer material 10 , the top layer 12 also protects the underlying layers and has generally no tack at room temperature.
- the basis weight of the top layer 12 generally may vary from about 2 to about 70 g/m 2 . Desirably, the basis weight of the top layer 12 may vary from about 20 to about 50 g/m 2 , more desirably from about 25 to about 45 g/m 2 .
- the top layer 12 can generally include one or more coats or layers of a film-forming binder and a powdered thermoplastic polymer. The composition of the coats or layers may be the same or may be different. Desirably, the top layer 12 will include greater than about 10 percent by weight of the film-forming binder and less than about 90 percent by weight of the powdered thermoplastic polymer.
- the top layer 12 includes from about 40% to about 75% of the film-forming binder and from about 20% to about 50% of the powdered thermoplastic polymer (based on the dry weights), such as from about 55% to about 70% of the film-forming binder and from about 25% to about 40% of the powdered thermoplastic polymer.
- each of the film-forming binder and the powdered thermoplastic polymer can melt in a range of from about 65° C. to about 180° C.
- each of the film-forming binder and powdered thermoplastic polymer may melt in a range of from about 80° C. to about 130° C.
- Manufacturers' published data regarding the melt behavior of film-forming binders or powdered thermoplastic polymers correlate with the melting requirements described herein. It should be noted, however, that either a true melting point or a softening point may be given, depending on the nature of the material. For example, materials such as polyolefins and waxes, being composed mainly of linear polymeric molecules, generally melt over a relatively narrow temperature range since they are somewhat crystalline below the melting point.
- Melting points if not provided by the manufacturer, are readily determined by known methods such as differential scanning calorimetry. Many polymers, and especially copolymers, are amorphous because of branching in the polymer chains or the side-chain constituents. These materials begin to soften and flow more gradually as the temperature is increased. It is believed that the ring and ball softening point of such materials, as determined, for example, by ASTM Test Method E-28, is useful in predicting their behavior in the present invention.
- the molecular weight generally influences the melting point properties of the thermoplastic polymer, although the actual molecular weight of the thermoplastic polymer can vary with the melting point properties of the thermoplastic polymer.
- the thermoplastic polymer can have an average molecular weight of about 1,000 to about 1,000,000.
- other properties of the polymer can influence the melting point of the polymer, such as the degree of cross-linking, the degree of branched chains off the polymer backbone, the crystalline structure of the polymer when coated as a layer, etc.
- the powdered thermoplastic polymer may be any thermoplastic polymer that meets the criteria set forth herein.

- These transferable layers were easily removed from the area surrounding the shape with little peel force required (i.e., by hand) as shown in FIG. 3 .
- the remaining transferable layers defining the shape cut were transferred to a 100% cotton T-shirt material as shown in FIG. 4 , at a transfer temperature of 375° F. for 25-30 seconds.
- the heat transfer material was allowed to cool, and then the base sheet was peeled away.
- Table 1 shows the images formed using cross-linked color layers.
- Table 2 shows the images formed using non-cross-linked color layers.
- Table 3 shows the images formed using cross-linked and non-cross linked color layers 16 and colored intermediate layers 14 .
- Table 4 shows the images formed using no color layer 16 and using non-cross linked colored intermediate layers 14 .
- Design 1 uses a relatively thick cross-linked color layer and provides better color opacity when applied to very dark substrates. This thicker color layer along with a relatively heavy intermediate layer provides improved cover of substrates with heavy weaves. Design 1 may be peeled hot or cold. Dark substrates with tight weaves would be better suited for Design 2.
- Design 2 is similar in construction to Design 1 except that the thickness of the cross-linked color layer of Design 2 is reduced. Design 2 is better suited for application to light or dark tighter weaved materials which tend to be lighter in weight and more flexible in hand. A thinner cross-linked color layer yields a more flexible and stretchable transfer than Design 1. Design 2 may be peeled hot or cold.
- Design 3 is similar in construction to Design 2 but with a non-cross-linked color layer. Both employ a heavy intermediate layer mainly for the benefit of improving the hold out of the color layer and its opacity. Design 3 would function well on heavy weave materials. Since the color layer is not cross-linked it would not necessarily have the strength to withstand the forces exerted by hot peeling and it is best suited for peeling cold. Design 3 shows the greatest color vibrancy on white fabric and tends to have good flexibility.
- Design 4 is similar to Design 3 in that the color layer is not cross-linked. However, Design 4 has no intermediate layer. It may or may not have an outer layer. Design 4 may or may not have a tie layer, depending upon the selection of the binder in color layer and the selection of the release layer. Design 4 relies upon the fact that the color layer is not cross-linked and the colored layer binds to the substrate it is being transferred to. Since the color layer is not cross-linked it may lack the strength to withstand the forces exerted by hot peeling and it is best suited for peeling cold. This design demonstrates best suitability for tight weave materials and shows the greatest color vibrancy on white fabric. Design 4 also exhibits the softest hand.
- Design 5 has a relatively thin cross-linked color layer in combination with a colored intermediate layer.
- the intermediate layer utilizes a polyurethane binder.
- Permax 202 is used rather than Sancure 2710.
- Permax 202 softens at a lower temperature than Sancure 2710 resulting in better penetration into the substrate (t-shirt).
- Permax 202 exhibits greater stretch than Sancure 2710.
- a cross-linked colored layer is incorporated to maintain greater opacity when applied to dark colored fabrics at high temperatures.
- Design 6 utilizes no cross-linked color layer. Instead all color is developed by using a colored intermediate layer.
- Permax 202 is the preferred binder for this embodiment due to its high stretch and ability to soften and bond to substrates, especially at elevated temperatures.
- a top layer is used but it is optional.
- a top layer can serve to help prevent roll blockage. And at the same time it aids in bonding to substrates. If application temperatures are expected to be low then a thicker top layer is preferred. In such low temperature cases the top layer will be performing the majority of the bonding.
